FML & FM10 2 different levels of player class

hi i have noticed probably with alot of FML players that there is quite a large gap in quality of regens in FM10 to FML for example i have a save game with a striker that has 16 finishing composure,acceleration,off the ball and pace and he is the most valuable striker on the game but in FML there are players that get 20's in all there key attribute areas for there position why is the difference is class between players on the game such a large margin ? just wondering and could it be made so that the FM10 players develop to the standard of the FML ones because its abit weird
